Accelerator pump rebuild kit for many of the late 70's and early 80's Honda's. This kit comes with the diaphragm with a 89mm long rod attached, spring, o-ring and a rubber boot for the rod. Get that CB pulling like it should with a fresh accelerator pump! If you're planning to rebuild the carbs and replace all the gaskets, it's a good idea to replace the accelerator pump as well. Check to see if there are any cracks or holes in the diaphragm, if there are, it needs to be replaced.Replaces Honda part numbers: 16021-MC9-771, 16021-393-004, 16201-393-014, 16021-KB7-671, 16021-426-003, 16021-460-771Replaces K&L Part Number: 18-2807Note: Could be used on the CMX250C Rebel from 1985-1987 but the rod needs to be cut.
